Join us online for an informative presentation from Jeffrey A. Jansen, Engineering partner, The Madison Group about Creep Failure of Plastics.
This presentation will address one of the most important, yet least understood, plastic failure mechanisms, creep rupture. Creep is the tendency of a polymeric material to deform permanently under the influence of continuous stress. It occurs as a function of time through extended exposure to levels of stress that are below the yield strength of the material. Given sufficient time, this can lead to creep rupture. Plastic materials are particularly prone to creep rupture through exposure to static stresses, and a recent study indicates that 22% of plastic failures are associated with creep.
The relatively high frequency of creep failure is linked to the widespread lack of awareness and understanding of the effects of time on polymeric materials, particularly at the design stage; the unique difference in time dependence between polymeric materials and metals; and the increasing use of plastic materials in diverse applications with longer time demands.
The concept of creep is extremely important to manufacturers and users of plastic components.
This webinar will cover:
- Introduction to Creep
- Creep Failure Mechanism
- Generalizations of Creep
- Creep Testing and Lifetime Projection
- Creep Failure Case Illustration
Jeff is a proven plastic professional with more than 30 years of experience solving problems and addressing opportunities related to polymeric materials. He specializes in failure analysis, material identification and selection, as well as compatibility, aging, and lifetime prediction studies for thermoplastic materials.
